How much vibration does sound actually cause an object. I tried humming near various objects and noticed nothing. I used to be really interested in early mechanical microphones and sound recording, but I couldn't find much information on how they work either.

- PeterisP 12y agoYour eyes wouldn't be able to see a 2000 Hz vibration, most vibrations that we perceive as sounds (except from the very low vibrations) are so fast that even with a huge amplitude they'd be just a motion blur for our eyes. Now, a 2000 fps camera can see things that a naked eye can not.
- Houshalter 12y agoBut I should see a blur or something, unless it happens to be vibrating at exactly the frame rate of both of my eyes (and even that would cause some weird effects, see helicopter blades spinning.) Almost missed your comment btw.
